Abstract
Magnesium (MgO), aluminium (Al2O3), and silicate (SiO2) combine to form cordierite ceramic, which is widely used in applications needing high resilience to
thermal shock. Because of its limited thermal expansion and strong electrical insulation, cordierite ceramic is a valuable material. When tested for resistance to
external force, cordierite, on the other hand, demonstrated minimal mechanical strength. It is to learn more about the effects of different calcium salt coatings on the mechanical and biological properties of pure calcium salt solutions (calcium chloride (CaCl2), calcium acetate (C₄H₆CaO₄) solution, calcium nitrate (Ca(NO₃)₂) solution) and a bioactivity test, which involves immersing the sample in a simulated bodily fluid, are all being used in this study to see what effect they have on cordierite. The reason why the pellet need to coating with the calcium salt is, to see which calcium salt produce formation of hydroxyapatite faster. The function of calcium salt in this experiment will act as a catalyst. As a result of characterization testing, cordierite showed a favourable reaction to hydroxyapatite production under the scanning electron microscope (SEM). The apatite peaks in the XRD study suggest that apatite has formed. Bioactivity test results show an increase in intensity on the bonding in Fourier transform infrared spectroscopy (FTIR). Results reveal that cordierite obtained from this study has the potential to be used as a bone implant material, and this is the conclusion reached.
